Description

Technical Field

[0001] This utility model relates to the field of battery equalization modules, and more particularly to a battery equalization module with an expansion port. Background Technology

[0002] Traditional fixed-length battery equalization modules cannot adapt to changes in the number of batteries by adjusting the length of the equalization module casing. Therefore, different casing lengths require different equipment molds for production.

[0003] There is a battery equalization module housing with a six-sided detachable structure. The upper and lower housings can be cut to the required length according to the number of batteries during actual assembly. However, this structure requires tools to adjust the length, and the cutting is often uneven, resulting in misfitting end caps and large gaps after installation. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a battery equalization module with an expansion port, which solves the problems of inconvenience in adjusting the length of the outer shell of existing battery equalization modules and the tendency for large gaps to appear after assembly.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A battery balancing module with an expansion port includes two symmetrically arranged shells, a left end cover, and a right end cover. The two shells, the left end cover, and the right end cover are detachably connected to each other. The inner wall of the shell has a plurality of first grooves sequentially formed along the length of the shell. The first grooves penetrate the entire inner wall of the shell in the width direction. The outer wall of the shell has a plurality of second grooves sequentially formed along the length of the shell. Each second groove is directly opposite a first groove.

[0007] Optionally, a plurality of the first slots and a plurality of the second slots are distributed at equal intervals along the length of the interlayer shell, and the plurality of the first slots and the second slots are located at one end of the interlayer shell.

[0008] Optionally, a plurality of the first and second slots are located at both ends of the interlayer shell, providing another implementation method, in which slots are opened at both ends of the interlayer shell, thereby allowing length adjustment operations to be performed at both ends of the interlayer shell.

[0009] Optionally, an opening is formed on the right end cover, and an expansion interface passes through the opening and penetrates the right end cover. A retaining ring is fixed on the outer surface of the right end cover opposite the opening. Several protective plates are fixed at equal intervals on the top surface of the retaining ring. A crease is formed on the protective plate opposite the upper edge of the retaining ring. The folded part of the protective plate covers the retaining ring. Several protective plates cover the entire opening of the retaining ring along its length. A locking strip is formed on the inner side of the folded part of the protective plate. A limiting strip is fixed on the bottom inner wall of the retaining ring. The locking strip cooperates with the limiting strip.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] 1. This utility model features a first groove and a second groove at the ends of the inner and outer walls of the shell. By weakening the strength of the grooves, the shell length can be adjusted by hand. The groove design keeps the cut straight, and when installed with the end cap, it maintains the integrity and sealing of the shell, effectively avoiding the interface gap problem caused by traditional cutting, and significantly improving the convenience of shell length adjustment and structural reliability.

[0012] 2. This utility model protects the expansion interface of the power balancing module by arranging a retaining ring and multiple protective plates on the right end cover, thus preventing the interface from being directly exposed. The multiple protective plates can be opened according to the position of the connector plugged into the expansion interface, while ensuring that the other protective plates remain closed, thus ensuring a good protection effect at all times.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1, please refer to Figures 1 to 3 This embodiment provides a battery equalization module with an expansion port, including two symmetrically arranged intermediate shells 1, a left end cover 2 and a right end cover 3. The two intermediate shells 1, the left end cover 2 and the right end cover 3 are detachably connected to each other. The assembly process of the entire shell is all existing technology, such as using buckles or bolts for connection, so it will not be described in detail here.

[0020] A number of first grooves 4 are sequentially opened on the inner wall of one end of the shell 1 along the length direction of the shell 1. The first grooves 4 penetrate the entire inner wall of the shell 1 in the width direction. A number of second grooves 5 are sequentially opened on one end of the longitudinal outer wall of the shell 1 along the length direction of the shell 1. Each second groove 5 is directly opposite a first groove 4. The number of first grooves 4 and the number of second grooves 5 are evenly distributed in the length direction of the shell 1.

[0021] By setting a first groove 4 and a second groove 5 on the inner and outer walls of the intermediate shell 1 (i.e., the upper and lower covers in the prior art), and arranging the grooves at the ends of the intermediate shell 1, when adjusting the length of the entire battery equalization module shell according to the number of batteries, it is not necessary to use tools to cut the length of the intermediate shell 1; it can be bent directly by hand. The arrangement of the grooves reduces the strength of the intermediate shell 1 at the groove positions, making the length adjustment of the intermediate shell 1 more convenient and quick. Compared with the cutting method, since the straightness of the grooves is relatively straight, the cut can remain relatively flat after being bent open. After the end caps at both ends are installed, the entire shell can remain relatively sealed, and there will be no gaps at the interface.

[0022] An opening 6 is formed on the right end cover 3. An expansion interface 12 passes through the opening 6 and penetrates the right end cover 3. The expansion interface 12 is located on the control plate. The control plate is installed inside the shell 1. A retaining ring 7 is fixed on the outer surface of the right end cover 3, facing the opening 6. Several protective plates 8 are fixed at equal intervals on the top surface of the retaining ring 7. A crease is formed on the protective plate 8, facing the upper edge of the retaining ring 7. The folded part 9 of the protective plate 8 covers the retaining ring 7. Several protective plates 8 cover the entire opening of the retaining ring 7 along the length of the retaining ring 7. A locking strip 10 is formed on the inner side of the folded part 9 of the protective plate 8. A limiting strip 11 is fixed on the bottom inner wall of the retaining ring 7. The locking strip 10 cooperates with the limiting strip 11.

[0023] When connecting the expansion interface 12 to the external wiring, the protective plate 8 can be opened accordingly. The engaging strip 10 can be pulled out past the limiting strip 11 to remove the retaining ring 7. When engaging the protective plate 8, the folded portion 9 of the protective plate 8 is flipped so that it covers the opening of the retaining ring 7, and the engaging strip 10 extends into the retaining ring 7 past the limiting strip 11, completing the engagement. The protective plate 8 protects the expansion interface 12, preventing it from being exposed. The multiple protective plates 8 ensure that even if one part of the expansion interface 12 is wired, the remaining parts of the expansion interface 12 are still protected.

[0024] Example 2, please refer to Figure 4 This embodiment provides a further technical solution based on embodiment one. The inner walls at both ends of the shell 1 are provided with a plurality of first grooves 4 in sequence along the length direction of the shell 1. The first grooves 4 penetrate the entire inner wall of the shell 1 in the width direction. The two ends of the longitudinal outer wall of the shell 1 are provided with a plurality of second grooves 5 in sequence along the length direction of the shell 1. Each second groove 5 is directly opposite a first groove 4. The plurality of first grooves 4 and the plurality of second grooves 5 are evenly distributed in the length direction of the shell 1. The first grooves 4 and the second grooves 5 are provided at both ends of the shell 1 so that the length of the shell 1 can be reduced simultaneously from both ends of the shell 1.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
